Transport across junctions of pseudospin-one fermions
Sourav Nandy, K. Sengupta, Diptiman Sen
We study transport across ballistic junctions of materials which host pseudospin-one fermions as emergent low-energy quasiparticles. The effective low-energy Hamiltonians of such f…
Steady states of a quasiperiodically driven integrable system
Sourav Nandy, Arnab Sen, Diptiman Sen
Driven many-body quantum systems where some parameter in the Hamiltonian is varied quasiperiodically in time may exhibit nonequilibrium steady states that are qualitatively differe…
Periodically driven integrable systems with long-range pair potentials
Sourav Nandy, K. Sengupta, Arnab Sen
We study periodically driven closed systems with a long-ranged Hamiltonian by considering a generalized Kitaev chain with pairing terms which decay with distance as a power law cha…
Aperiodically driven integrable systems and their emergent steady states
Sourav Nandy, Arnab Sen, Diptiman Sen
Does a closed quantum many-body system that is continually driven with a time-dependent Hamiltonian finally reach a steady state? This question has only recently been answered for…
Entanglement generation in periodically driven integrable systems: dynamical phase transitions and steady state
Arnab Sen, Sourav Nandy, K. Sengupta
We study a class of periodically driven dimensional integrable models and show that after drive cycles with frequency , pure states with non-area-law entanglement entrop…
